These are some index funds with fidelity that are cheaper than Vanguard. I'd be interested in the Fidelity 500 Index Premium.
Fidelity 500 is a fine mutual fund, but there are several others that are even better in terms of diversity and cost. All of the following (and in the Bogleheads link) are either at the same or better than cost wise/performance to Vanguard, or near as dammit considering you also get the benefit of Fido's slightly better customer service.
https://www.bogleheads.org/wiki/Fidelity^all the comparable funds to Vanguard's stable of mutual funds.
I have my entire portfolio with Fido, and I use the following:
Fidelity Total Market Index Fund (FSTVX)
Fidelity U.S. Bond Index Fund (FSITX)
Fidelity Real Estate Index Fund (FSRVX)
^Small amount in a real estate fund (this is absolutely unnecessary for most everyone, but I personally like a tiny % since I like the idea of real estate, but not the actual hassle of being a landlord or otherwise keeping up with real estate stuff)
I do not personally hold any international anything as I subscribe to the idea that the U.S. market contains enough companies that have a worldwide presence, but if you do want a percentage in international, Fido does offer several strong comparable funds (to Vanguard).
That's it - 3 funds total across all my accounts, zero cost for management (self manage), zero service or buy/sell fees, and a very low average (between 0.045-0.09%) on my expense ratios. I have access to my portfolio through their website, can contact my personal rep or just call up a random rep if I feel like it, or go visit a storefront for any questions. As long as you steer clear of their managed funds (and the best they have for low expense and diversified is in that Bogleheads link) you get stellar service and performance for dirt cheap pricing.
If any rep tries to lead and or pressure you to do anything other than index funds, tell them you'll have to think about it and then come here and ask for help. But also, they don't hard sell (at least they're not supposed to!) so just stay firm in needing time if that's what it takes and they should be quite helpful and not push you into anything you don't feel comfortable with (and definitely do some reading here, at Bogleheads, and ask lots of questions if you need to!!)
Good luck with everything. I'm so sorry you got in with the EJ crowd, but you are a smart cookie to start questioning things and taking control. Some folks never take the blinders off and are too scared of ever learning how things work enough to see how they are being taken advantage of, so good for you!!
